摘要:
Devices and methods for sleep detection involve the use of an adjustable threshold for detecting sleep onset and termination. A method for detecting sleep includes adjusting a sleep threshold associated with a first sleep-related signal using a second sleep-related signal. The first sleep-related signal is compared to the adjusted threshold and sleep is detected based on the comparison. The sleep-related signals may be derived from implantable or external sensors. Additional sleep-related signals may be used to confirm the sleep condition. A sleep detector device implementing a sleep detection method may be a component of an implantable pulse generator such as a pacemaker or defibrillator.
摘要:
Methods and systems for evaluating a pathological condition include acquiring movement information, such as electromyogram (EMG) information, and sleep disordered breathing (SDB) information, and detecting the presence of a pathological condition using both movement and SDB information. Methods may involve sensing physiological signals including at least muscle movement signals. Sleep-related disorders are detected using the sensed physiological signals, the sleep-related disorders including at least an involuntary muscle movement disorder and sleep-disordered breathing. Methods and systems also provide for detecting and treating a sleep-related disorder using movement and SDB information. Cardiac, respiratory, nerve stimulation, drug, or a combination of such therapies may be delivered to treat a detected or diagnosed pathological condition.

摘要:
Methods and systems are directed to delivering cardiac pacing therapy to a patient. A pacing therapy associated with one or more pacing parameters is delivered. Alternate cardiac pacing therapies associated with one or more alternate pacing parameters are transitioned to, based on a sleep/wake cycle of the patient. Interactions between the pacing parameters of the pacing therapy and the alternate pacing parameters are resolved. Resolving pacing parameters may be based on analysis of lower rate limits and/or lower rate hysteresis, for example.
摘要:
Methods and systems provide an integrated approach to respiratory and cardiac monitoring, diagnosis and/or therapy. A medical system includes one or more cardiac electrodes coupled to an external respiratory therapy device. The cardiac electrodes sense cardiac electrical activity that is used to generate an electrocardiogram (ECG) signal. Cardiac events, such as arrhythmia, myocardial infarction and/or ischemia, may be detected based on the sensed cardiac electrical activity.

摘要:
Systems and methods involve an implantable device configured to perform at least one cardiac-related function, a patient-external respiratory therapy device, and a communication channel configured to facilitate communication between the implantable device and the respiratory therapy device. The implantable and respiratory therapy devices operate cooperatively via the communication channel to provide one or more of patient monitoring, diagnosis, and therapy. The communication channel may be configured to facilitate communication between an external processing system and at least one of the implantable device and the respiratory therapy device. The processing system is communicatively coupled to at least one of the implantable and respiratory therapy devices via the communication channel to provide one or more of patient monitoring, diagnosis, and therapy.
摘要:
Systems and methods provide for gathering of patient related data during non-sleep periods and modulating a therapy delivered to the patient during sleep using the gathered data. Data associated with a patient is gathered while the patient is awake. A therapy delivered to the patient during patient sleep is adjusted using the acquired data. The therapy delivered to the patient may include one or more of a respiratory therapy, such as a positive airway pressure (xPAP) therapy, a sleep disordered breathing therapy, a cardiac rhythm management therapy, such as a cardiac overdrive pacing therapy, a medication therapy, or a drug delivery therapy. The therapy delivered to the patient may be optimized using the acquired data.
摘要:
Systems and methods involve automatic activation, de-activation or modification of therapies or other medical processes based on brain state. A medical system includes a sensor system having one or more sensors configured to sense signals related to the brain state of the patient. A brain state analyzer detects various brain states, including sleep stage and/or brain seizures. A controller uses the brain state detection information to control a medical system configured to perform at least one respiratory or cardiac process. Methods involve sensing signals related to brain state and determining the brain state of a patient based on the sensed signals. At least one respiratory or cardiac medical process is controlled based on the patient's brain state.
摘要:
Methods and systems provide an approach to therapy control based on assessment of a patient's cardiopulmonary status. Conditions sensed via sensors of an external respiratory therapy device are used to assess a patient's cardiopulmonary status. The respiratory therapy device sensors may be utilized alone or in combination with other sensors to determine cardiopulmonary status of a patient. Therapy delivered to the patient is controlled based on the cardiopulmonary status assessment. For example, therapy delivered to the patient may be initiated, terminated, and/or modified based on the assessed cardiopulmonary status of the patient. Cardiopulmonary status assessment, therapy control, or both, are performed by an implantable device.
